peppermints are nice to have but mine seem to disappear, probably were taken care of by my emerald crab? I just bought some of that Joes Juice for the first time this last weekend and I can say that this stuff does work. I still have some little ones that I missed but hopefully I'll get them the next time. I was and still am skeptical about this stuff but hey it did get rid of some ugly looking stuff in my tank and that all that matters right now.
